The blinking patterns of HP LED lights
The blinking patterns of HP LED lights are diagnostic indicators. They blink to communicate a specific problem. If an LED blinks, note the pattern and contact an authorized service provider or your authorized reseller for service. To find the authorized service provider or authorized reseller in your area, go to the HP website (in English) and type your product model number with the word warranty in the search field. The blinking lights can be either red or green, depending on the product model.
The sequences are as follows:
1 blink followed by a short pause: An error has occurred. System is disabled. Please try again after re-enabling the system.
1 long blink followed by 2 short blinks: Memory error detected. Please install new memory modules to continue using system features. Note that if you install new memory modules, you must remove all current modules before installing the new ones and then restart the computer for it to detect and use the new memory modules correctly.
5 short blinks every 1 second: System Board failure detected. Please contact an authorized service provider or your authorized reseller for service and support options appropriate for your country/region before taking further action on your own as opening up your computer without proper grounding could lead to serious injury or damage to your computer components from electrostatic discharge (ESD).

The HP LED lights and error codes
The HP LED lights on the front of the computer indicate different states, conditions, or errors. Depending on the model of HP computer you have, there could be four to nine lights. Different sets of light patterns indicate different conditions.
The HP LED lights can be solid or blinking (flashing), depending on the error condition. If the computer does not have an LED to indicate a specific condition, the pattern of blinks is descriptive.
Each blink pattern is made up of sets of long and short blinks with pauses between them. A long blink followed by two short blinks indicates a problem with either the system board or BIOS (basic input/output system). A long blink followed by one short blink indicates a problem with either memory or an expansion card in slot [x]. A long blink followed by three short blinks indicates a problem with the processor (CPU). The location of the error is indicated by [x].
If all nine lights blink simultaneously, this indicates a CPU problem. If eight lights blink simultaneously, this indicates a problem with either power to the system board or an energy-saving feature such as suspend mode [or hibernation]. If seven lights blink simultaneously, this indicates a problem with either power to an expansion card or one of the devices on that card.
The HP LED lights and troubleshooting
The HP LED lights on the front of the computer indicate different things, depending on their color. Here’s what the different colored HP LED lights mean, and how you can troubleshoot them if they’re causing problems.
The Power LED lights are located on the front panel of the computer. These can be lit up in red, green, or blue, depending on the model of your HP computer.
The meaning of the Power LED lights can differ depending on whether your computer is on or off. When your computer is off, a steady or blinking light indicates different states:
-A solid white light means that the power supply is working and providing power to the system.
-A blinking white light indicates that there is a problem with the power supply. This could be due to a faulty power supply, incorrect voltage setting, or a short circuit. If you see a blinking white light, check your power supply and voltage setting first. If those are both okay, then you may have a short circuit somewhere in your system.
-A solid red light means that there is no power being supplied to the system. This could be due to a faulty power supply or an incorrect voltage setting. If you see a solid red light, check your power supply and voltage setting first. If those are both okay, then you may have a short circuit somewhere in your system.
-A blinking red light indicates that there is a problem with the system’s ability to generate enough power to run all of its hardware properly. This could be due to an insufficient power supply, incorrect voltage settings, or failing hardware components. If you see a blinking red light, check your power supply and voltage setting first. If those are both okay, then you may have failing hardware somewhere in your system
The HP LED lights and warranty
The HP LED lights on the back of the machine indicate the warranty status of your device. The color of the lights will tell you if your warranty is active or has expired. The number of blinking lights will tell you how many days are left on your warranty.
Active warranty: All four LED lights are solid white.
Warranty expired: The first LED light is solid red and the other three are off.
Days left on warranty: The first LED light is blinking red and the other three are off. The number of times the first light blinks before it stays on steady indicates how many days are left on your warranty. For example, if the first light blinks four times before it stays on steady, you have four days left on your warranty.
